Abstract

Carbon-based water-induced generators (WIGs) with unique advantages offer a promising method for autonomous power generation. However, the traditional configuration still suffers from low output power. Herein, we introduce a promising WIG with high power output achieved via a multistrategy approach for a self-driving intelligent water positioning platform. By rationally using electrokinetic regulation and synergism of galvanic effects, the optimal WIG enables the output of an open-circuit voltage of ∼823 mV and a short-circuit current of ∼109 μA, with a power density of 3.9 μW/cm², ∼62.4 times higher than previous reports under DI water. Additionally, such design demonstrates superior stability and versatility in multiple aqueous solutions and allows for the enhancement of output energy via series or parallel connections for low-power devices. As a proof of concept, a valuable self-powered positioning system has been successfully fabricated via our outstanding WIG integrated with lifesaving and mini positioning devices for immediate water rescue. Our proposed design has opened up an avenue for the iterative development of high-efficiency WIGs, promoting them toward valuable applications.

自驱动系统的多策略方法促进水致发电

碳基水致发电机（WIGs）以其独特的优势为自主发电提供了一种很有前景的方法。然而，传统的配置仍然存在输出功率低的问题。在此，我们介绍了一种有前途的高功率输出WIG，通过多策略方法实现了自动驾驶智能水域定位平台。通过合理利用电动力学调节和电效应的协同作用，优化后的WIG在DI水中输出开路电压为~ 823 mV，短路电流为~ 109 μA，功率密度为3.9 μW/cm2，是以往报道的62.4倍。此外，这种设计在多种水溶液中表现出卓越的稳定性和通用性，并允许通过串联或并联连接提高低功率设备的输出能量。作为一个概念的证明，一个有价值的自供电定位系统已经成功地通过我们卓越的WIG集成了救生和微型定位装置，用于即时水上救援。我们提出的设计为高效wig的迭代开发开辟了一条途径，促进它们走向有价值的应用。
